Constellation Energy (CEG) stock has lost 20% over the past twelve months, trailing the S&P 500 and its 17% return. Yet recent business developments present a stark contrast to that market decline. On October 6, 2026, Google agreed to buy nuclear power from Constellation for 20 years, arriving just days after Amazon signed a similar deal. For investors who held the stock through its recent drop, these technology partnerships may look like a turning point. So where would a gain over the next three years have to come from?
Constellation's Power Regions Would Have To Bring In More
All of it would have to come from higher sales across the regions where Constellation operates. In a Trefis scenario, Constellation stock would be worth about 77% more in three years, with revenue growth accounting for the entire gain. This model holds the P/E at today's level and assumes a slightly lower net margin. The table below compares today's figures against that scenario.
The scenario assumes sales will grow 22.1% a year, below the 26% growth recorded over the twelve months to fiscal Q2 2026. Constellation has reached that growth rate in only one of its last three years.
Sales rose 5.4% in the twelve months to fiscal Q2 2025, and they fell 10.8% in the twelve months to fiscal Q2 2024. However, recent results align more closely with the projection. Sales climbed 23.0% from a year earlier in fiscal Q2 2026. During fiscal 2025, its two largest segments expanded quickly, as sales rose 17.5% in the Mid-Atlantic and 20.8% in the Midwest. Meanwhile, the third largest segment, Other Power Regions, grew 1.4% during the same year.
Are Big Customers Still Committing To Constellation's Power?
The short answer is yes. During the fiscal Q2 2026 earnings call on August 6, management noted the company had signed about 920 megawatts of long-term nuclear deals since the previous call. These contracts run 18.5 years on average. Today, roughly 30% of Constellation's clean baseload output, the steady power its plants produce, is secured under long-term agreements. These deals cover power Constellation already produces. Management also said the company is working toward returning the Crane nuclear plant to service in the second half of 2027.
Demand from major technology companies continues to build on that foundation. Google's 20-year agreement arrived after that call and adds 890 megawatts of new nuclear capacity. The deal will fund upgrades at 11 existing Constellation nuclear units. Management's latest guide is for earnings, not sales. In August, the company raised its 2026 adjusted operating earnings range to $11.50 to $12.50 a share.
How Constellation's Payoff Shrinks If Growth Or Profit Slips
The following table illustrates the three-year upside when a single assumption changes while the rest remain constant.
Among the downside risks modeled, a net margin reverting to its three-year average of 10.1% cuts into the return most severely. Even in that outcome, the majority of the projected gain remains intact. The scenario assumes the share count holds at today's level, though the count rose about 11% over the last three years. If the count continues to climb, the value of each individual share will yield less than the scenario projects.
The entire gain is driven by sales, so the case depends on sales growth holding up. Growth would have to drop to 0.9% a year in order for three years of owning the stock to return nothing. That break-even mark sits 25.1 points below the growth of the latest twelve months. History, however, offers a note of caution: Constellation's sales fell 10.8% in one of its last three years.
Constellation is undeniably securing large corporate customers. Its sales growth trajectory is less settled, as only the latest year has matched the pace mapped out in the scenario. Delivering sales growth close to 22% again in the next quarterly report, expected on or around November 4, 2026, would signal that the recent surge was more than a one-off event. If growth drops back toward the pace of earlier years, Constellation becomes a riskier bet. The company would then be reliant on nuclear capacity that is still to come.
Does This Mean You Should Act On CEG?
Our purpose is to inform you with unique data so you make the right investment decisions. That said, betting on a single stock is always risky, no matter which direction you choose.
There is a smarter approach. Since its inception, the Trefis High Quality (HQ) Portfolio has returned 105%, beating the benchmark that combines the three major indices - the S&P 500, S&P Mid-cap, and Russell 2000. And it did so without taking the concentrated risk that comes with do-it-yourself stock picking. If that is how you want to invest, the HQ Portfolio is the place to start.
